OK … There are a lot of feline aliens in SF, for whatever reason: quite possibly it's because of the habitat they share with so many writers, i.e. the keyboard. Anyway, what I'm looking for here are the names of three dog-alien races. These should be intelligent, and probably bipedal, canines or canine-analogues. I've been trying to think of as many as I can and I'm finding it quite tricky, so any and all sources of science fiction are acceptable. Fantasy and horror fiction examples are not permitted: no werewolves!

Hmm, time to pull resources? The only one I can think of is a Remoolian from MiB (all movies), whose true form resembles a pug, albeit with a dark green color, antennas, and a 3-pointed tail, according to Men in Black: The Series. I hope that the resemblance of form may be enough to be allowed by Big D.

Jeez, there's some dross out there on the subject of dogs-in-space/alien canids. Trying to find a coffee bean in all that dung is painful - thanks, Big D.
Another thing is the cover art - if you're gonna put sunglasses on an animal, don't put them on an alsatian, put them on a pig!

There are at least two SF role-playing games with intelligent canine races … one is pretty obscure, but the other is just about as mainstream as these things get (especially from an Elite perspective).
